Independent power bench for the Starlink Mini
How much power does a Starlink Mini really need?
The Mini averages 25–40 W Official spec: From a Starlink specification sheet or help article. Checked Oct 5, 2026; the Standard dish 75–100 W Official spec: From a Starlink specification sheet or help article. Checked Oct 5, 2026. Turn that into hours on your battery and solar for your state, then buy the smallest setup that works.
For anyone running a Mini or Standard dish away from a wall outlet: in a car, on a trail, at a job site or through an outage. Each number is tagged: Official: From a Starlink specification sheet or help article spec, Community: A dated measurement posted by an owner, cited owner reading, Planning: Our stated assumption, used until bench results replace it our assumption.

The six questions people ask first
- Runtime
How long will my battery run the Mini?
About usable Wh ÷ 44.4 W on USB-C at the top of Starlink’s range: a 512 Wh power station gives roughly 9 h 48 min.
- USB-C and 12 V
Can I power it from USB-C or my car’s 12 V?
Yes to both, with conditions: USB-C needs a 100 W (20 V / 5 A) PD source and Starlink’s USB-C cable; 12 V needs short, thick wire.
- Winter solar
How much solar do I need in December?
From 1.8× to over 7× the July panel size, depending on the state (NASA sun data). In Alaska, solar alone can’t carry a 24/7 dish in December.
- Power banks
Which power bank actually delivers its rated Wh?
None delivers 100% of its label. Our bench will measure the gap at the Mini’s 40 W profile; until results are in, we plan with 80% for power banks.
- Heat
Will it overheat?
The Mini is rated to 122 °F. It throttles, then shuts down, when it gets too hot: a closed case, a hot dashboard or still air in full sun are the usual causes.
- Mini or Standard
Mini or Standard for my use?
Mini for battery and travel use: roughly a third to half the watts. Standard for a fixed home install on mains power.

How this site is different
- Dataset
Every watt figure, with its source
Spec sheet, owner measurement or seller claim: labeled, dated, downloadable.
- First-hand
Battery delivery bench
Label Wh vs what a battery really delivers at the Mini’s input. Method published before results.
- Honest
What we haven’t tested
We don’t own a Mini. Every Mini number says where it came from.

Questions people ask
How much power does Starlink use?
Starlink lists the Mini at 25–40 W on average (about 15 W idle) and the Standard dish at 75–100 W (20 W idle), including the router and power supply, measured at the AC input.
Does Starlink work without electricity?
No. The dish and router need power the whole time. A battery, UPS, power station or generator keeps it running through an outage; see outage power.
Is this site run by Starlink?
No. It’s an independent site, not affiliated with SpaceX or Starlink. We don’t own a Mini; Mini figures come from Starlink’s specs and cited owner measurements, labeled on every number.
